Unmanned Aerial Vehicles have advanced rapidly in the last two decades with the advances in microelectromechanical systems (MEMS) technology. It is crucial, however, to design better power supply technologies. In the last decade, lithium polymer and lithium-ion batteries have mainly been used to power multirotor UAVs. Even though batteries have been improved and are constantly being improved, they provide fairly low energy density, which limits multirotors’ UAV flight endurance. This problem is addressed and is being partially solved by using docking stations which provide an aircraft to land safely, charge (or change) the batteries and to take-off as well as being safely stored. This paper focuses on the work carried out in the last decade. Different docking stations are presented with a focus on their movement abilities. Rapid advances in computer vision systems gave birth to precise landing systems. These algorithms are the main reason that docking stations became a viable solution. The authors concluded that the docking station solution to short ranges is a viable option, and numerous extensive studies have been carried out that offer different solutions, but only some types, mainly fixed stations with storage systems, have been implemented and are being used today. This can be seen from the commercially available list of docking stations at the end of this paper. Nevertheless, it is important to be aware of the technologies being developed and implemented, which can offer solutions to a vast number of different problems.

Az autonóm járművek, így többek között a pilóta nélküli légi járművek (UAV) irányításának egyik fontos területe a járművek kooperatív irányítása. A kooperatív irányítás során megvalósítandó célkitűzés a járművek mozgásának összehangolása egy előre megadott közös, globális cél megvalósítása érdekében. Ilyen cél lehet például az UAV eljuttatása megadott időben egy előre megadott helyre (például légi utántöltés, légi kötelék kialakítása, eljutás a megfigyelési helyre, eljutás a felderítés helyére, eljutás a harci bevetés helyére, eljutás megadott határszakaszra stb.). A szerző célja bemutatni néhány lehetséges UAV bevetési forgatókönyvet és repülési feladatot, és az ezeket megvalósító irányításokat és irányítási rendszerek alapkoncepcióit.

“…Most methods without optical cooperation mark replace the center point with the cone tracking frame point or the fitting cone center, but the theoretical center point in the actual docking process should be the oil pipe nozzle in the cone. The point accuracy is much lower than the method with optical cooperation mark [2,3], which results in the docking is limited to the oil pipe and needs to slide into the cone at the right angle to complete the docking. Therefore, it is necessary to propose a method that does not rely on the optical cooperation logo and improve the accuracy of the cone center point, which lays a higher foundation for the subsequent development of the autonomous air refueling technology.…”

In order to achieve high-precision docking of airborne refueling in close proximity, this paper proposes a high-precision cone center point extraction method based on stereo vision feature matching. Based on the detection and tracking results of the target cone, the method performs extended compensation on the tracking frame of the cone to form a region of interest (ROI). With camera calibration results and feature matching which is performed on the ROI, a depth map of the cone can be obtained. With the ideology of double Gaussian function, the center offset is solved according to the distortion ratio of the cone ring width to locate the cone center point. The method does not need to add any cooperation logo to the cone, and is easier to implement in the engineering application; it is not necessary to fit the cone-shaped circle to solve the center point, which can be directly solved; compared with other methods, the precision is greatly improved. This method has been implemented in ABB robot simulation system. The experimental results successfully verify the feasibility and effectiveness of the method.
